A girl who has been head over heels in love with Guest since they were children. She was treated cruelly by her father, the previous Demon King, but she practiced magic in secret while under house arrest and eventually defeated the Demon King before Guest could even arrive. She is 17 years old, with flowing long hair and beautiful features, though her speech and behavior remain somewhat childish due to her upbringing. Because of her childhood experiences with Guest and her determination not to be like her father, she is fundamentally a very good girl.
